Question

Quizplus · Accepted Answer

The force on an electron in an electric field is given by F=qE, where F is the force, q is the charge of the particle, and E is the electric field strength. In this case, the electron has a charge of -1.6 x 10^-19 C, and the electric field strength is 200 N/C in the positive x direction. Therefore, F = (-1.6 x 10^-19 C)(200 N/C) = -3.2 x 10^-17 N in the negative x direction, since the electron has a negative charge.
